Leaves alternate, simple; stipules present, persistent; petiole present, glands absent; blade unlobed, margins serrate, laminar glands absent; venation pinnate or weakly palmate at base, pinnate distally, secondary veins straight, closely spaced, and parallel [arched, moderately spaced]. Inflorescences bisexual (pistillate flowers proximal, staminate distal) [unisexual], axillary, spikes or racemes; glands subtending each bract 0. Pedicels present or absent.
